Solution for lg(x+3)+lg(x-3)=lg(6) equation:


Simplifying
lg(x + 3) + lg(x + -3) = lg(6)

Reorder the terms:
gl(3 + x) + lg(x + -3) = lg(6)
(3 * gl + x * gl) + lg(x + -3) = lg(6)
(3gl + glx) + lg(x + -3) = lg(6)

Reorder the terms:
3gl + glx + gl(-3 + x) = lg(6)
3gl + glx + (-3 * gl + x * gl) = lg(6)
3gl + glx + (-3gl + glx) = lg(6)

Reorder the terms:
3gl + -3gl + glx + glx = lg(6)

Combine like terms: 3gl + -3gl = 0
0 + glx + glx = lg(6)
glx + glx = lg(6)

Combine like terms: glx + glx = 2glx
2glx = lg(6)

Reorder the terms for easier multiplication:
2glx = 6gl

Solving
2glx = 6gl

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-6gl' to each side of the equation.
-6gl + 2glx = 6gl + -6gl

Combine like terms: 6gl + -6gl = 0
-6gl + 2glx = 0

Factor out the Greatest Common Factor (GCF), '2gl'.
